Attention:

getTimezoneOffset (), which returns the time difference between GMT and local times, is a single digit in minutes . To get the seconds *60.

The getTimezoneOffset () method returns the number of minutes between the local time and the GMT or UTC time. In effect, the function tells us the time zone where the JavaScript code is running and whether the specified time is daylight saving.

Returns are measured in minutes, not hours, because some countries have time zones that are even less than one hours apart.

D.gettimezoneoffset ()-480an article:Recently done a real estate of the second kill, group buying e-commerce site (the house also has a second kill, shot not small AH), which has a seconds to kill the countdown display, mainly to determine the current time distance seconds to kill the beginning of how much time, there are seconds to kill the start and kill the end of various displays. The main point is that the so-called current time can not use the browser through the new Date () to obtain the client time, so long as the user modifies their own machine time so the countdown will be chaotic, so this current time must use the server time, So using a static cache page so this current time using Ajax method for reference: http://www.blogjava.net/dongbule/archive/2012/01/10/368229.html
